Abstract: Information is arranged within a predetermined shape. The predetermined shape is captured in an image taken by a tangible image-capturing element of a device which captures images at the direction of a user. The device includes a tangible processor that analyzes the image captured by the image-capturing element to determine whether a predetermined shape is present in the image. The tangible processor determines an alignment of the predetermined shape when the predetermined shape is present in the image, and reads data within the predetermined shape in accordance with the determined alignment. The device automatically forwards a request for content over a communications network in accordance with the data read within the predetermined shape. The device receives the content over the network and displays the content.

Abstract: An amplifier may include two or more pulse-width modulators (PWMs) controlling respective sets of switches to produce an amplified version of a source signal. The clocking for the amplifier may be controlled to delay signal processing within the PWMs relative to one another in time, thereby providing an effective time offset between the absolute moment in time of the edge transition of the controlling signals to the respective sets of switches. The PWMs may include a decrementor that counts down to zero from the next PWM duty-cycle value when a new data sample is detected, beginning a new count when the next sample is present. The PWM output may correspond to the counter value, outputting a pulse when the counter value is nonzero. A “data-sample-ready” signal may be decoded from a master counter, which may be clocked based on the high speed PWM clock, and the delay mechanism may be based on adjusting the decode value to determine when the PWM should initialize to the next data sample.

Abstract: A loudspeaker radiating diaphragm can be stiffened to help increase the breakup frequency to above the working frequency range of the driver concerned, by forming it of a molded part and an attached formed part. The molded part is a radiating surface with stiffening ribs. The formed part is a thin surface of high modulus material, attached to the rear of the ribs. The overall structure can have significantly higher stiffness than either of the two parts. This helps in designing a loudspeaker driver that does not breakup within its working frequency range.

Abstract: A multi-leaf collimator for a radiotherapy apparatus comprises at least one array of laterally-spaced elongate leaves, each leaf being driven by an associated motor connected to the leaf via a drive means so as to extend or retract the leaf in its longitudinal direction, the drive means comprising a sub-frame on which at least a subset of the motors are mounted, the sub-frame being mounted at a location spaced from the leaf array in a direction transverse to the lateral and longitudinal directions, and including a plurality of threaded drives disposed longitudinally, each being driven by a motor and being operatively connected to a leaf thereby to drive that leaf.

Abstract: Information and data stored by a mobile device is protected by comprising applying password-protection to the locally-stored information without persistently storing the corresponding password locally. Rather, the corresponding password is stored by a remote password server. In response to a trigger event on the mobile device, such as an unlocking action by the user, a request is sent by the mobile device to the password server to retrieve the corresponding server, and the corresponding password is returned to the mobile device. The mobile device can then use the password to access the protected information. If the user determines that the mobile device is lost, stolen, or out of the user's physical control, the user may access the password server and disable the sending of the password to the mobile device, thereby thwarting attempts to access the protected data on the mobile device.

The present invention also relates to herbicide formulations containing at least one herbicidal active comprising glufosinate-ammonium, a hydrotrope comprising sodium octane sulfonate, and an adjuvant comprising a sodium salt of C8 ether sulfate, wherein the weight ratio of the herbicide active to the adjuvant is about 1:1. The present invention also further relates to methods of providing pesticide protection to an agricultural crop by applying the pesticide formulations of the present invention to the crop.

Abstract: A web application decomposed into one or more domain sandboxes ensures that the contents of each sandbox are protected from attacks on the web application outside that sandbox. Sandboxing is achieved on a per-element basis by identifying content that should be put under protection, generating a secure domain name for the identified content, and replacing the identified content with a unique reference (e.g., an iframe) to the generated secure domain. The identified content is then served only from the generated secure domain using a content handler.

Abstract: An amplifier may include two or more pulse-width modulators controlling respective sets of switches to produce an amplified version of a source signal. A positive DC-offset based on the source signal may be applied to the pulse-width modulator controlling one respective set of switches, and an equal value negative DC-offset may be applied to the pulse-width modulator controlling the other respective set of switches, to provide an effective offset between the respective points in time of the rising/falling edges of the different pulse-width modulated control signals. The addition of alternating positive and negative DC-offset values doesn't affect the output load, and doesn't degrade the signal. The DC-offsets may be added at a frequency selected to be beyond the signal baseband, and the value of the small input signal level may be determined using an RMS level comparator or similar measurement technique.

Abstract: A loudspeaker comprises a reflex port located within the enclosure at a point substantially co-incident with a nodal surface of at least one resonant mode within the enclosure. The amplitude of that resonance at the input to the duct is minimized, hence assisting in filtering out the effect of that resonance without needing absorptive material. Ideally, it is placed at the intersection of two or more nodal surfaces.

Abstract: The present invention provides a loudspeaker with at least two diaphragm assemblies, in which the reactive forces acting on the magnets in each assembly cancel. By linking the two magnets together via a non-rigid material, resonance in the drive assemblies is highly damped and corresponding distortion of the loudspeaker output is reduced.
